What I claim in the video is that the ECB did give a prominent role to the analysis of the changes in broad money up to 2003, when it reviewed its strategy, and not surprisingly it led to a higher rate of growth of money in the Eurozone in the years running up to the Global Financial Crisis. Just to be clear, I do not support that any central bank should adopt a ‘mechanistic’ monetary growth policy rule, by which the bank adheres to an intermediate M3 (or broad money) rate of growth target come what may. The link between money and prices and nominal income is indeed very strong over the medium and long term, but it is of course affected by other variables/phenomena in the short term that need to be properly considered and taken into account by policy makers. So rather than a mechanistic approach to such a monetary target, changes in money growth should be given a primary role in assessing inflation and nominal income forecasts, and thus in the making of monetary policy decisions; and this is precisely what the ECB did from 1999 to 2003 under its two-pillar strategy. So when money growth continuously exceeds the rate deemed to be compatible with monetary stability, this would signal inflationary pressures and even financial instability the central bank would eventually tackle by tightening its monetary policy. This rationale would show the commitment of the central bank to both monetary and financial stability over the long term, and the use of a broad monetary aggregate would serve as a credible indicator to make monetary policy decisions and as a means to transmit the central bank’s expectations on inflation and output growth.
